This invention relates to water heaters and more particularly to automatic water heaters, and an object of this invention is to provide a device of the type set forth having an improved and simplified construction.

A further object is to provide a device of the type set forth which will be easy and cheap to manufacture and assemble and rugged and durable in operation.

These and other objects which will be obvious to those skilled in this particular art are accomplished by means or" the invention illustrated in the accompanying drawings, wherein Figure 1 is a sectional view of a water heater constructed in accordance with one embodiment of this invention. Fig. 2 is similar view of a part thereof. Fig. 3 is a horizontal sectional iew on the line 33 of Fig. 1;

l is a view on the line 4: l of Fig. 2; and Fig. 5 is a top plan view partly in section,

of a detail, taken on line 55 of 1.

The particular embodiment of this invention which has been chosen for the purposes of illustration includes the usual b "ner housing 5 enclosing the burners 6, pilot light 7 and other associated apparatus such as is well known in this particular art.

The upper end of the housing is provided with an outwardly entending annular shoulder 8, an upwardly extending circular flange 9 and an inwardly extending annular ledge or flange 10. The ledge 10 is provided with an inwardly extending bracket 11 for supporting the adjacent portion of a water supply pipe 12 extending into the heater from the usual water motor 13. A heating coil 14, of any desired configuration, is connected to the curved end 15 of the water supply pipe.

As illustrated, the heating coil is shaped like a plurality of truncated cones so as to have spaced coils of alternately large diameter 16 and small diameter 17 with coils of graduated diameter therebetween.

The heating coil is supported upon a coil supporting rod 18 by means of supporting plates 19 secured to the rod and provided with outwardly extending coil supporting sections 20 engaging the coil 17 of small diameter adjacent the supporting rod. The supporting plates 19 also constitute bailies for insuring 1926. Serial No. 108,291.

direct cont-act between the coils and the heating gases, and for preventing a stream of the latter from flowing upwardly through the enter of the coils without directly contactng therewith. The lower end of the rod is irovided with a bifurcated yoke 21 which rests upon the supply pipe 12. A heat confining shell 22 is supported upon the inwardly extending ledge 10 of the base 5 and an outer casing 23 is mounted upon the annular shoulder 8 so as to enclose the shell 22 and form therewith a heat insulating air chamher at. The upper end of the coil supporting rod 18 is provided with a member 25 having radial supporting arms or spokes 26 engaging the edge of a perforation 27 formed in a lid asap.

28, having an annular shoulder 29 resting upon the upper edge of the casing 23. An outlet pipe 30 is connected to the upper end of the heating coil and extends outwardly through the shell 22 and casing 23. The assembly is secured together by through bolts 31 extending upwardly through the air chamber 2% from the ledge 10 and through openings 32 formed in the lid 28 and by means of W which the lid is clamped to the ledge 10 with the casing 23 therebetween.

It will be noted that two through bolts, only one of which is shown, are all that is required for holding the entire heating chamber assembly together. By means of these bolts the lid 28- forces the casing 23 downwardly on the supporting ledge and the outlet pipe 30 is, in turn, made to press the shell downwardly onto its supporting ledge, and the entire assembly is thus held securely together.

The base member 5 is provided with an angularly extending flanged bracket 33 by,

means of which the device may be supported upon the wall bracket 3i having a central heater-supporting section 35 spaced from an associated wall 36 and the lower portion of the housing 5 is provided with a perforated bracket 37 adapted to be superimposed on the horizontal perforated portion 38 of a wall brace 39 as shown in Fig. 2. Bolts 40 are used to secure the bracket 37 to the flange 38.

W hat I claim as new and desire to secure by Letters Patent is:

The combination in a Water heater, of a, burner chamber having a surrounding Wall provided with an outwardly extending annular shoulder at the top thereof, a casing positioned above said Wall and supported on said shoulder, an inwardly emending ledge on said wall adjacent to said shoulder, a lid positioned on said casing and a through bolt passi; through said lid and said ledge for clamping said casing against said shoulder.

In testimony whereof, I have hereunto sub scribed my name this 7th day of May. 1926.
